Issues with 5GHz on new XE75
I just upgraded from the Deco M9 plus to the deco XE75. I had no issues with devices on the M9 network but with the ever growing smart home I decided to upgrade to the XE75. I integrated the XE75 into the existing network and prioritized the routers as suggested by TP link, making the XE75 the main Deco. I've noticed that my iPhone 11 Pro Max will not connect to my main Deco network if the 5GHz is enabled along with 2.4 but has no issues if it's just set to 2.4. Also I have no problem connecting to the guest network that only 5GHz is enabled. I had no issues with 5 and 2.4 being enabled on the old M9 network. Any suggestions why all of a sudden this is happening?
